Add a global parameter that can be applied to custom queries query parameters so the parameter can be defined prior to executing the queries. Allow the use of these params in custom queries so the query can be run with settings of imported data, allowing full customisation/transformation of data within Spotfire. Passed to the func that kicks of the queries. Similar to the linking of a document property to parameter but with the addition of having the option to import data. So probs a different type of parameter? Maybe: Allow this parameter to be set during the runtime or scheduling.
